Side channels attacks in code-based cryptography

The McEliece and the Niederreiter public key cryptosystems (PKC) are supposed secure in a post quantum world because there is no efficient quantum algorithm for the underlying problems upon which these cryptosystems are built. The CFS, Stern and KKS signature schemes are post-quantum secure because they are based on hard problems of coding theory. The purpose of this article is to describe what kind of attacks have been proposed against code-based constructions and what is missing
